Perhaps you should try some spelling variations:
chinh doanh » kinh doanh
tieu sach » chieu sach, dien sach, te sach
luan nang » luan van, van nang
luan san » luan van, luan hoan, luan phan
cong tan » cong san, cong thanh, cong ty
cong tac » cong ty
toan cau » toan cao, toan ban, toan tap

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: theo tieu sach - chinh doanh ((luan nang) OR (luan san)) ((cong tan) OR (cong tac)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu sach - chinh doanh ((luan nang) OR (luan san)) ((cong tan) or (cong tac)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo tieu sach - chinh doanh ((luan nang) OR (luan san)) ((cong tan) or (cong tac)) toan cau*.
